Everything Hurts

My whole body hurts... My ribs, legs, hips. Starting to have a hard time breathing (which I understand is normal). Still extremely nauseous and haven't been able to really eat since I got pregnant and I'm 12 weeks today. (I am over the moon about this baby but I did NOT expect pregnancy to be THIS hard) I feel like I can't handle being pregnant (anxiety and hormones don't mix well).

Any advice on the body aches or the nausea or how to better cope?? (Already set up a therapist)
